I ran Seafoam on my 96 Integra GSR with 165,000 miles, and it ran so so so so so so so much better, the idle was completly smooth after, and while driving it felt like it gained at least 10-15 HP. It may have been such dramatic results because the car had 165K, but WOW! P.S. Change your oil and spark plugs after, maybe even your O2 sensors because mine stopped working after the seafoam. You will not regret it.

you only get smoke when you do it through the PVC or booster line, not the gas tank. I just did this again yesterday and this time I only got about 5 sec of white smoke and slight hesitation, guess the engine is clean.

Worked wonders in my 89 Jeep with high miles. I threw that sucker in the crankcase and in the gas. Put some of the leftovers in my BMW, same spot. Did not notice a difference in the BMW, but the Jeep I did, granted, the BMW has only 61 K on it. This weekend going to throw some in the wifes Mustang 5.0 vert, has over 140K on it. I imagine it will help alot. Just my experience.

I did mine right before I filled up the tank. I think it was 2/3 of the bottle. The can said how much. Did notice a little bit more responsiveness after a while, but no miracles. All in all, def worth the 6 bucks...

I just seafoamed according to the DIY found here. Everything worked out well, engine runs considerably smoother and I have a much better response. However, the check engine light came on after I reconnected the intake...

I have to get an axle replaced, so i'll just bring it to BMW to see what they say (I am assuming O2 sensor...). Nevetheless, the car runs wonderfully. A huge difference, I just wish the check engine light didn't come on...

Take it to Autozone and have it scanned. They can print out the code so will give you a heads up before you go to the dealer. Actually, most autopart stores have them, the first one I went to would not clear the code....said..."We can't do that." He also had no clue what he was doing, I had to show him the port, then he could not unplug it, had to do it for him. He did after pimp buying a 150 dollar one so I can do it myself....LOL. If you meet someone like that, just drive up the street to another store.

I believe (I'm not at my house so I can't check) that it's a lean fuel mixture in both banks. You probably tore the intake boot while you were playing with the airbox. I did it to mine once. The boot costs a whopping $15 at the dealer but it took about two hours to change it.
